Hmmm.  I was about to say that the LGPL already grants explicit approval
of converting to GPL, but I just realized there's a problem with tsql
binaries:

$ ldd src/apps/.libs/tsql 
        libreadline.so.4 => /lib/libreadline.so.4 (0x40027000)
        libtds.so.1 => /usr/lib/libtds.so.1 (0x40050000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x40069000)
        libssl.so.0.9.6 => /usr/lib/libssl.so.0.9.6 (0x4007d000)
        libcrypto.so.0.9.6 => /usr/lib/libcrypto.so.0.9.6 (0x400a9000)
        libc.so.6 => /lib/libc.so.6 (0x40163000)
        libncurses.so.5 => /lib/libncurses.so.5 (0x4027e000)
        libdl.so.2 => /lib/libdl.so.2 (0x402bd000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

libreadline is GPL, and libssl is GPL-incompatible, so this binary is not
redistributable.  Unfortunately, I just checked sqsh, and it has the same
problem.  I'm going to see how feasible it is to have freetds link
against gnutls instead of openssl.  The other option is to use editline
instead of readline.
